Answer:
2 corresponding to 6
3 corresponding to 7
Step-by-step explanation:
Corresponding angles just make the letter F
Answer:
42
Step-by-step explanation:
The height of the pole is 4 times shorter than the length of the shadow 20÷5=4
The height of the building must be 4 times shorter than its shadow length 168÷4=42
Answer:
34 Deg
Step-by-step explanation:
Since the Triangle is isoceles, each of the internal base angle = 180-107=73
Sum of internal angles =180, Angle4= 180-(73+73)= 180-146=34
Answer:
12.566
Step-by-step explanation:
A = ∫1/2(r)^2dtheta from a - b = 0 to 2π
∫1/2(sin^2theta-4sintheta+4)dtheta
[9/4theta+2costheta-1/8sin2theta] from 0 to 2π…
when you solve this you get 14.137 without taking out the cos(2theta+3)
